Dacrotized chains: Dacrotizing is a process of metal coating. The compositions are proprietary water based coating dispersions containing metal oxides, metallic zinc and aluminium flakes. The zinc and aluminium platelets align themselves in multiple layers forming a metallic silver gray coating. Overlapping zinc and aluminium flakes provide an excellent protective barrier and the zinc corrodes to protect the steel. Due to the concentration of aluminum within the coating, the result is good bimetallic corrosion resistance. Damaged areas in the coating will fill with zinc oxides and carbonates, thus repairing itself. The dacrotizing process can be applied to numerous types of chains.
